  • Patent number: 8786240
    Abstract: The invention realizes a method for controlling an electric cylinder and a control system for the cylinder that can prevent a load for pressurizing from significantly exceeding a target load and can shorten the time for the pressurization. A servo controller 17 can set the speed of the rod 11 and a load for stopping Ps that is used for determining whether the rod 11 should be stopped so that the load for pressurizing Pm does not significantly exceed the target load Pt. The servo controller 17 drives the rod 11 under the position control mode and determines whether the load for pressurizing Pm that is detected by a load detector 13 is bigger than or equal to the load for stopping Ps.

  • Patent number: 8749180
    Abstract: The present invention is aimed to realize a method and a system for controlling an electric cylinder by which the load detector that is attached to an electric cylinder and the rod of the cylinder can avoid being overloaded. An unexpected bump between the rod of the cylinder and the material to be pressed can cause that overload. A servo controller 17 determines whether the load for pressurizing Pm detected by the load detector 13 is larger than or equal to the load for detecting a bump Pc. If it is determined that the load for pressurizing Pm is larger than or equal to the load for detecting a bump Pc, the servo controller 17 determines whether the flag for stopping is ON. Also, the controller 17 determines whether the speed Sm of the rod 11 is greater than or equal to an allowable speed to bump Sc.
